After reading up on mixes. Shoot, I realized I used too much sand in mine!!!! About 50%. I planted trichos in it using porous clay pots and am now wondering if this will be detrimental as it seems water trickles down slowly through it. :[
Was hoping if I adjust the watering I can leave them there for about a year...... It does get rainy in winter, here in S. Cali, but, I will bring my plants under shelter at that time.

Advice?
